Abstract: ABSTRACT OF THE DISCLOSURE      A fuel injection pump has a metering valve for controlling the delivery of fuel by the pump and a speed-responsive mechanical governor for adjusting the metering valve.  The governor provides a force tending to close the metering valve and acts through a lever against the bias of an idle speed control spring.  The lever engages the idle speed control spring through a cantilever mounted flat leaf spring with a flat bi-metal leaf inter-posed between the lever and the leaf spring.  The bi-metal leaf increases the biasing force of the idle speed control spring when temperature deviates from a preset temperature in either direction.

Abstract: Hans Pfefferkorn, Schillerstr. 4, 654 Simmern Bernd Pfefferkorn, Goethestr. 6, 654 Simmern Viktor Reiter, An der Schneiderburg 2, 654 Simmern Stopper Device Abstract of Disclosure A tamper-proof bottle stopper intended to be used for closing bottles. The stopper means is of a composite nature and in-cludes a stopper body having an integral upper flange portion which is situated in the closed position above the annular end surface of the neck of a bottle and abuts against the latter when the stopper body proper is pressed into the neck. The upper portion of the stopper body is corrugated or fluted on the radially outer surface thereof. The stopper body defines a cavity open at the upper and and closed at the lower end. If wanted, a cylindrical stopper of cork is pressfitted into said lower portion. The composite stopper means further includes a fluted cap that engages and coacts with the fluted portion of the stopper body so as to prevent a rotary motion of the cap relative to the stopper body. The cap is provided with a skirt pro-jecting downwardly on the outer surface of the neck of a bottle. The cap, and more particularly its skirt, are of relatively small diameter and of a resilient material adapted to be expanded and mounted on a neck of relatively large diameter of a bottle and then to contract to said relatively small diameter. The cap in-cludes a readily removable annular tear-off strap which, when torn off, severs the cap peripherally, and allows removal of the stopper body and of its insert from the neck of the bottle. Projections on the inside of the skirt preclude removal of the cap without severing of the same by said strap.

Abstract: ABSTRACT OF THE DISCLOSURE          A gas furnace employs an exhaust flue damper driven by an electric motor equipped with position indicating switches. A gas flow detector switch supported in the gas line has a vertical passage and a valve member gravity biased into a rest position in which it blocks gas flow through the passage.   Fuel flow through the line creates a differential pressure on the valve, raising it above the rest position.  Circuitry interconnecting the damper drive  and position indicating switches and the gas flow switch with the furnace thermostat and the gas line control valve, posi-tions the damper in a closed position when there is no gas flow to the furnace and in an open position otherwise and prevents energization of the gas flow valve when the damper is closed.

Abstract: ABSTRACT         A digital control unit for a static converter contains a binary-coded counter which counts the pulses of an oscillator.  The counter outputs are connected to the address inputs of a function memory in which sawtooth or ramp functions are stored.  The numbers read out of the function memory are compared in a comparator, with a number determining the drive of the static converter.  The result of the comparison and pulses on selected outputs of the counter are linked, in a logic circuit, to form firing pulses for the static converter.  The invention is suitable for control units for static converters, in particular for AC control elements and inverters.  All expense of adjusting, and all compensation of drift errors is obviated.

Abstract: SEAL FOR A ROLLING CONE CUTTER EARTH BORING BIT Abstract of the Disclosure A seal acts as a barrier to the drilling fluid, pulverized cuttings and other materials in a borehole preventing the materials from entering the bearing area of a rolling cone cutter earth boring bit and retains lubricant inside the bearing area.  A rolling cone cutter is rotatably mounted on a cantilevered bearing pin extending from the bit body.  A "Z" seal is positioned between the cutter and bearing pin.  An outer rigid seal ring is positioned around the bearing pin.  The outer rigid seal ring is split to allow rad-ial expansion and contraction.  An inner rigid smaller diameter seal ring is positioned around the bearing pin.  The inner rigid seal ring is also split to allow radial expansion and contraction.  An elastomer ring is located between the inner and outer rigid rings and affixed to the rigid rings.  Fluid in the borehole causes the elastomer ring to force the inner rigid ring to contract into tighter contact with the bearing pin and the lubricant between the bearing pin and the rolling cone cutter causes the elastomer ring to force the outer rigid ring to expand into tighter contact with said rolling cone cutter thereby preventing the ingress or egress of fluid and materials.

Abstract: Abstract A method and system are disclosed for externally treating human blood, with the objective of reducing the func-tioning lymphocyte population in the blood system of a human subject.  According to the method, blood is withdrawn from the subject and passed through an ultraviolet radiation field in the presence of from about 1 nanogram to 100 micrograms per ml of blood, of a dissolved psoralen capable of forming photoadducts with DNA, to thereby effect covalent bonding between the psoralen and the nucleic acid of the lymphocytes, thereby altering the said nucleic acid and inhibiting the metabolic processes of the lymphocytes; and thereupon returning the irradiated blood to the subject.  The withdrawn blood may be formed into an extracorporeal stream and flowed through a treatment station whereat the irradia-tion is effected, as for example by exposure to W energy in the wave length range of from about 3200 to 4000 Angstroms; and such flow process may be conducted on a continuous basis.  If desired, at least portions of the treated blood may then be separated, as for example by a continuous centrifuge, before re-turning the remaining diverted blood to the subject.
